Percy Jackson never cried, never cooed, and never spoke. To his mother, he was a silent miracle-a child who seemed to feel the world rather than respond to it. But beneath the quiet exterior lay something far more profound: an understanding of things no child should know, and a voice that refused to be spoken aloud.
or
Percy Jackson is a Seer, a Siren, and a Child between the two faces of the Sea. Because he is a Seer, he is part of the Sun. Because he is a Siren, and Siren's always sing, he is part of the Sun. But extra attention from other Beings is always tragic, so the Sea tries to hide their Pearl from Them.
Which includes the Sun, and the Moon, and the Sky, and the Owl, and the Messenger, and the Beauty, and the War, and the Wine, and the Forge, and everyone else in the Divine Realm.
Y/N L/N was a regular child, what stood out was his personality, dark hair and vibrant blue eyes. Also the fact that he could never seem to stay out of trouble, he had almost superhuman strength and was fond of the sky. So one day when his small cabin in the woods is surrounded by women in sliver and an arrow nearly goes through his head, he freaks the hell out.
PS (If you don't like the PJO series don't read the story man, sounds like common sense to me, or you just don't like my story in general.)
